I just took a look over at ASUS UL30Jt manual (which is available on ASUS support page) and noticed that there’s an Intel WiMAX driver, meaning ASUS UL30Jt could be shipped with WiMAX-capabilities.
This isn’t surprising as HTC and Sprint just announced their first-ever 4G WiMax Android phone the HTC Evo.
I am not sure exactly how WiMax works but it could be that you might be able to sign up for 1 WiMax account (and maybe they give you a login and password) so you can also use it straight from your laptop without a WiMax USB dongle. At worst case, ASUS might be selling these laptops off Sprint’s new 4G WiMax service.
At any rate, it’s an indication that the ASUS UL30Jt perhaps will be more than we thought.
